reductant. The carbonyl cyclopropanes can be employed for both [2σ + 2σ] and [2σ + 2π] annulation with either alkenes/alkynes or bicyclo[1.1.0]butanes, yielding cyclopent-anes/-enes and bicyclo[3.1.1]heptanes (BCHs), respectively. BCHs are promising bioisosteres for 1,2,4,5 tetra-substituted aromatic rings. Mechanistic studies, including density functional theory computation and a trapping experiment

Dearomative photocycloaddition of monocyclic arenes is an appealing strategy for comprehending the concept of “escape from flatland”. This brings the replacement of readily available planar aromatic hydrocarbon units with a 3D fused bicyclic core with sp3-enriched carbon units. Herein, we outline an intermolecular approach for the dearomative photocycloaddition of phenols. In order to circumvent the
单环芳烃的脱芳香光环加成是理解“逃离平地”概念的一个有吸引力的策略。这使得现有的平面芳烃单元被具有sp 3富集碳单元的 3D 稠合双环核取代。在这里,我们概述了酚类脱芳香光环加成的分子间方法。为了规避基态芳香性并构建构象受限的结构单元,选择双环[1.1.0]丁烷作为偶联伙伴。这种脱芳香方法可以直接获得与环烯酮部分融合的双环[2.1.1]己烷单元,这进一步有助于作为后修饰的合成关键。机械实验主张根据氧化还原电位,两种反应物均可能发生。
